Description

Technical Field

[0001] The utility model relates to the technical field of thermal automatic control communication equipment, in particular to a thermal automatic control cabinet communication equipment. Background Art

[0002] Traditional methods have shortcomings in automatic control cabinet communication switching and fault alarm. Usually, traditional methods rely on manual monitoring of wired routing status and manual switching to wireless routing, which results in a long switching process and prone to communication interruption. In addition, traditional methods lack an automated fault alarm mechanism, and patrol personnel cannot obtain fault information in a timely manner, delaying the timing of fault handling. The relay and communication module failed to achieve automated control, resulting in low stability and reliability of the system. In actual operation, these deficiencies will lead to frequent communication interruptions, affecting the normal operation of the system and increasing the difficulty of maintenance and management. At the same time, the automatic control cabinet communicates through a wired routing. When the wired routing communication fails, it automatically switches to wireless routing communication to ensure that the automatic control cabinet communication is not interrupted. To prevent the operation of the thermal power station from being dangerous due to the interruption of the automatic control cabinet communication during winter operation, the practicality is poor and needs to be improved.
